HERE COMES THE "GM" CORN FLAKES-TAKE IT OR LEAVE IT!

GM food debate never seems to be ending and there is not even a single day when one does not hear about fresh controversies in one or the other part of the world. Latest to arrive is the news about the legal clearance granted in the US to a new variety of GM Corn which is rich in the starch splitting enzyme amylase. The rationale in approving this GM crop is that it is used only for making ethanol that is mixed with gasoline to create a bio-fuel blend that is being promoted in that country. The logic is that by using new corn variety the production cost for ethanol can be reduced significantly. This is illogical because the corn ethanol industry gets huge subsidies from the government running to billions of dollars and at best the new move by the government will only boost the income of this industry to astronomical levels. The moot question is at what cost to the health of the population? Unfortunately there is no way a consumer or any user can differentiate this GM corn from other normal and evolved varieties being used by the food and feed industry. As the new version of GM corn is not "intended" for consumption by animals and human beings, rigorous safety testing has not been done raising a number of questions regarding the advisability of clearing it, probably under pressure of the bio-fuel lobby.


"It warned: 'Syngenta's own scientific data released last month shows if this corn is co-mingled with other corn, it will have significant adverse impacts on food product quality and performance.' Association president, Mary Waters, said: 'USDA has failed to provide the public with sufficient scientific data on the economic impacts of contamination on food production.' The corn contains a powerful enzyme that breaks down the starch inside the plant, which is a cost saving function for ethanol production. The association said that it if were to enter the food processing stream, the same function that benefits ethanol production will damage the quality of food products like breakfast cereals, snack foods, and battered products. The concerns are all the more important because the association is a well-known supporter of GM crops and food. Director of the Britiish lobbying group, GM Freeze, Pete Riley, said: 'UK ministers are supporting EC moves to allow low level GM contamination of unapproved GM traits in animal feed and are reported to be pressing for an extension of this ill conceived policy to cover food imports as well. 'The history of the biotech industry in the US shows a trail of contamination incidents and Syngenta's starch decomposing maize will surely get into the food chain and create major economic problems and health scares".


Surprisingly even some of the pro-GM lobbyists are raising alarms regarding the consequences of allowing country-wide cultivation of the new high amylase corn variety that may result in unintended food contamination, and there is a need for the US Government to reconsider its decision. The issue assumes critical importance because many countries are considering limits of contamination of normal food crops with the GM versions and logically no country may allow such contaminants beyond 1%. International community must isolate the US on this issue and imports of foods from this GM-obsessed country must be banned under the aegis of WTO. It is time that the underlying belligerency on the part of this super power that it can do any thing without caring about the world opinion must be curbed through universal cooperation amongst the affected countries.

ENERGY "APPETITE"-CHINA TO IMPORT CORN



Diversion of food grains for production of ethanol for blending with gasoline and diesel has been blamed for the inflationary trend felt world over for the these staples. While Brazil leads the world in using sugarcane based ethanol for manufacture of blended automobile fuels, China is not far behind in taking this route. By 2010 China wants to reach a target of 6.7 million tons (mt) of blended ethanol and 11 mt of blended bio-diesel and ethanol for this purpose at present comes from wheat (60%), corn (20%), cassava (10%) and sweet potato (10%). If this trend continues there is going to be pressure on the food front.

"China is the world's second largest corn producer, but a growing appetite for grain combined with ambitious fuel ethanol targets may make the country a net corn importer, possibly as early as this year. China may become net corn importer despite move away from grain ethanol. At present, grain accounts for about 80 percent of biofuel feedstock, and consumers are finding themselves at increased competition with the country's burgeoning energy needs for limited domestic resources".

According to present plans Chinese government wants to avoid corn imports by expanding cultivation of Cassava, Sweet Potato and sweet Sorghum. How far such an objective will fructify remains to be seen. Though China hosts 20% of world's population, it has less than 7% of global farmland. The experience vis-à-vis Soybean should not be forgotten where in less than 15 years China became a massive importer of this commodity from a predominant exporter earlier. According many experts China does not possess necessary technology for cellulosic ethanol which is going to be most acceptable in future.

CORN ETHANOL-BETTERING THE YIELD


A new strain of bacteria isolated from compost dumps has been reported to be efficient in increasing ethanol yield from corn when used to process the spent residue to recover another 15-20% alcohol. Touted as a plug-in technology for the existing corn ethanol plants, the developers claim that there is lot of energy economy as no drying or disposal steps for the spent material is necessary besides increasing the profitability significantly. Investment cost for installing additional processing system will have to be considered before coming to a conclusion regarding the viability of the new technology.

"Biofuels are currently made mainly from food crops such as grains, vegetable oils and sugar cane, which has led to debate about whether they might help to drive up food prices. They are seen as a way to reduce emissions of the greenhouse gases believed to contribute to climate change but environmental groups have questioned the green credentials of some processes, including U.S. corn-derived ethanol".

Present practice of diverting corn for ethanol production under the fossil fuel reduction strategy in some developed countries like the US is already being frowned upon by the global community in the face of massive food shortages in many parts of Africa, Asia and South America. If there is an international commitment on preventing diversion of food crops to non-food use, most of the ethanol plants may have to be closed making the new plug-in technology redundant. Probably the strain of bacteria may still be useful for converting cellulosic materials into ethanol.
